You know Quinton "Rampage" Jackson? No? So, maybe you heard about his widebody Challenger? It was featured in Forza Motorsport 4.
That's a rim from that car - exactly it's front rim of it (rear is much wider and deeper). Since FM4 don't have deep version (or mine rip, who knows) in LOD0, I did that I had.
IT HAVE REALLY BIG OFFSET!- it's best to use with widebody cars.

PS: It comes in 19x11 size, since there's really low amount of cars, which fit 24" rims.
PPS: Somebody have working offset script (source)? The one I have had weird bug, so I don't use it this time.
